Abstract

Pulp and paper industry is one of the most important and growing industrial sectors in the world. Global pulp and paper production continues to increase along with rising demand from year to year. The pulp industry generally uses hardwood for Kraft pulp production which is also integrated with paper mills. The Kraft process uses a mixture of sodium hydroxide and sodium sulfide, which is known as white liquor. Improving productivity, pulp quality and cost efficiency is the main focus in facing global competition. Efforts to research and apply new technology continue to be carried out to increase pulp yield without reducing the quality. This study aims to evaluate the techno-economic performance of Kraft pulp production through Compact Cooking and Lo-Solids technologies. Techno-economic analysis (TEA) is carried out by using Microsoft Excel with the scope is started from pulp cooking until bleaching. It focuses on optimizing cooking conditions and analyzing variable costs like wood chips, chemicals and utilities to compare economic profitability. The finding suggests that Lo-Solids technology is more cost-effective than Compact Cooking, providing a basis for further process improvements. Kraft pulp production from Compact Cooking gives profit margin around 148 USD/ADt, while Lo-Solids give profit margin around 189 USD/ADt.
